The "agentless" mode make the server-side DaemonSet optional, now, you can start debugging by using the command kubectl debug --agentless without pre-installing any server-side components.

In addition, we documented some practical examples of using kubectl-debug to help users getting started.

Thanks for @caruccio @gregwebs @klzsysy for reporting and fixing issues. A great thanks to @tkanng who contributes the major features of this release!
